Specification of Letters Patent.

Patented May 12, 191.4.

Application filed J uly 18, 1913. Serial No. 778,793.

To all whom it may concern Be it known that I, HENRY S rornnn, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented a newand useful WatenCooler, of which the following is a specification.

- This invention relates to improvements in water coolers and more particularly tov a cooler formed of a casing and two tanks disposed one within the other and the compartments defined by which, starting with the central compartment, receive therein the cooling medium, the'liquid to be cooled, and a heat insulating materialrespectively.

The construction further includes two separate covers, capable of acting as a tunnel for the insertion of the liquid to be-cooled.

A further object is to provide a cooler which will be simple and cheap in construction, which will maintain the liquid and cooling medium in a cool condition and rotect the same against the absorption of lieat from the external sources.

With the foregoing and other objects in view whichwill appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departingirom the spirit of the invention.

In the drawings accompanying this specification and forming a "part hereof, the preferable form of my invention is shown, in which Figure 1 is a vertical sectional view taken on a longitudinalor central plane of the cooler. Fig. 2 is a horizontal sectional view of the cooler.

Referring to the drawings in which similar reference numerals designate corresponding parts throughout the several views, 3 designates an open ended cylindrical tank which in the present drawings is provided with a coolin medium disposed therein in the form 0 ice 4. Completely surrounding the tank 3 is a larger tank 5 which receives a suitable liquid therein and which liquid is-cooled by contacting with the ice containing tank 4., v

A casing 6 is provided, relatively larger than tank 5, and is provided with a. removable bottom 7. The cylindrical casing 6 is outwardly flared at its lower extremity as at 8 providing a suitable base upon which the entire cooler rests' The upper extremities of the tank 3 and casing-6 are provided with the, curved rims 9 and 10 which engage the upstanding flanges 11 of an annular top 12. The upper extremity of the tank 5 is provided with the outlying flange 13 which abuts the under surface of the annular shaped top and in order to prevent the relative movement of the tanks, the connection between the cover and the side walls of the tanks may be soldered, welded, or so secured that the spaced relation of the tanks as illustrated in Fig. 1 will be maintained. the smaller of which is The lower extremity of the tank 3 is provided with the downwardly extending feet 14 so thatthe weight of the entire tank will not be brought to bear upon the top 12. The top 12 is provided with an opening 15 therein which communicates with the liquid compartment defined by the tanks 3 and 5. A suitable plug- 16 fits within the opening 15 and prevents dust or other foreign material from entering therein but does not effect a sealed joint therewith such as would substantially prevent the escapement of the liquid through the faucet 17. In this connection it mlght be mentioned that a somewhat similar faucet 18 communicates with the central tank 3 and provides for a suitable draining of the drip water therefrom of the ice 4 which is the ordinary and usual COOliIlg medium.

In order to protect the water cooler from the absorbing of heat in the top or upper portion, the inner cover 19 is provided the greatest diameter of which is approximately equal to the diameter of the tank 5 so that it protects the tanks 3 and 5. The inner cover 19 as illustrated in section in Fig. 1

is in the form of an inverted funnel when acting as a cover and when positioned as shown in dotted lines, serves as a funnel for the filling of the liquid tank. A second or outer cover 20 is provided, the largest diameter of which is substantially equal to the diameter of the casing 6 so that the cover in question spans the entire top of the cooler and effectually protects and insulates the samefrom heat. The covers 19 and 20 are dome-shaped ance and at the same time provide an air so as to present a neat appearchamber of maximum volume, which as is wellv known is a good insulator for heat.

The compartment defined by the tank 5 and casing 6 is filled with some material having a high coeilicient of thermal resistance, sawdust being an example of the same. In order to. insure that the sawdust or other material-used as an insulating substance will be properly packed between the tank and casing, the bottom 7 is provided and the entire cooler inverted during the positioning of the insulating material in place. Also by providing the removable bottom 7 and inverting the cooler during the positioning of the sawdust therein, it insures that a compact layer will be had beneath the bottom of the tank 5 so that the weight of the ice and liquid will be transferred through the said heat insulating material and directly to the outstanding flared base 8, thus relieving the annular cover of considerable weight and making the entire device more rigid in structure. Alsothe removing of the bolts 21 allows the bottom 7 to be removed and the heat insulating material to be removed should it be necessary or advisable.

Having thus described the invention, what I claim to be new and original with me is A cooler comprising a central ice receiving tank, a second liquid containing tank embracing the same and defining a liquid cool- 1 ing compartment, said ice receiving tank provided with downwardly extending feet spacing the bottom of said tank above thebottom of said liquid receiving tank, a cylindrical casing inclosing the said tanks and spaced a distance therefrom, an annular sloping top common to said tanks and casing, the said annular top provided with upturned peripheral rims, the central tank provided with an overhanging curled edge engaging the inner peripheral rim of said cover, the outer casing provided with an inturned curled upper edge embracing and interlocking with the outer peripheral rim of said top, a funnel shaped inner cover fitting over said ice and liquid receiving compartments and adapted to act as a tunnel for the filling of said liquid receiving compartment, and an outer cover provided with a depending ledge fitting'over and engaging the curled edge of the said outer casing.

In testimony that, I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.

HENRY STOFFEL.
